ADJUSTABLE LAMP.

To all whom it may concern:

Be it known that I, FRED C. HOWE, a citizen of th e'United States,residing atNeW' Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inAdjustable Lamps, of which the following is a specifi-.

the shaft 13, having a hand wheel 14 upon cation, reference being hadtherein to the accompanying drawings.

My invention relates. to a new and 1mproved adjustable lamp of that typewherein the lamp may he moved aboutv a'central point, and has for itsobject, among other things, to simplify and make more positive theconstruction of this type of lamp with the fewest possible parts.

To these, and other ends, my invention consists in the adjustable lamp,having certain details of constructionand combinations of parts, as willbe hereinafter de-' scribed and more particularly pointed out intheclaims.

Referring to the drawings, in which like numerals of reference designatelike parts in the several figures, Figure l is a fragmentary side viewof my improved lamp with the parts within which it is mounted shown insection; Fig. 2 is anend view thereof, partly in section; Fig. 3 is anenlarged side elevation; and Fig. l is an enlarged fragmentary portionthereof, showing in detail the construction and arrangement of thepinion with the disk adjacent thereto.

My invention is particularly designed for use upon automobiles, whereinit is desirable that the rays of light from the lamp may be thrown toany pointwithin'a limited zone about a central point, although notlimited thereto, as its adaptability with other mechanismsand inotherplaces is quite apparent.

In the drawings, the fixed part 'to which my improved lamp is connectedis designated by the numeral 1, upon both sides of which are the collars2+2. lVithin these. collars and the part 1 is rotatably mounted theshank 3 of the guide ball at, through which is a. straight slot5parallel to the axis of said shank.

Partly surrounding the guide ball 4, and

maintaining a movable contact therewith, is

the cup 6, having an irregularlyshaped opening 7 therethrough with aprojecting lip 8 thereon parallel with and adjacent to the edge 9 ofsaid opening. Fixed within said opening is a plate 10, the outer edge ofPatented June 1 55, 1915.

cured to the cup 6 by the bridges 12 so that the edge of the plate 10containingthe teeth 11; is substantially parallelwith, the face 9 of theopening 7. Secured to the cup 6 is the lamp body 19-, within which isalamp20.

Rotatably mounted within the shank 3 is one end and a pinion 15 upon itsopposite.

end, the teeth of said pinion meshing into the teeth 11 and therebymoving the cup 6 about the center of the ball 4; as the shaft 13 isrotated, during which time the stud. 16

trayels in the slot 5 guiding the said cup 6. This engagement of thepinand slot always insures the retention of the cup 6 in any of its severalpositions. Endwise movement of the pinion 15, whereby it may becomedisengaged from the teeth 11, is prevented by the washer 17 thatisrotatably mounted upon the screw 18,'threaded into the shaft The thumbscrew is threaded through the spindle 3 and impinges against the shaft13 s0 as to lock the shaft against rotation and hold the lamp in any ofits se'iieral posi tions.

'As minor changes and alterations can be made within my invention, Iwould therefore have it understood that I do not limit myself. to theexact construction herein shown and described, but claim all that fallsfairly within the spirit and scope of my. invention.

.Having described my invention, what I claim as new and desire to secureby'Letters Patent, is I 1. The combination with a globular member; of acup member with an irregularly shaped opening therethrough partlysurrounding said globular member and having a movable engagementtherewith; a toothed plate within said opening; means for securing thesame so that there is anopen space aroundthe entire edge thereof andinside the edge of the opening in said cup member, and means for movingsaid cup about said globular member, comprising a rotary shaft having amember thereon operatively engaging said toothed plate.

2. The combination with a globular mem ber; of a cu member with anirregularly shaped opening therethrough partly surrounding said globularmember and having a movable engagement therewith; a plate Within saidopening having teeth around the entire edge thereof; means for securingsaid plate to said cuo member, and means for moving said cup about saidglobular member, comprising a rotary shaft having a. member thereonoperatiyely engaging said plate.

3. The combination with a globular member; of a cup member with anirregularly shaped opening therethrough "partly. surrounding saidglobular member and having a movable engagement therewith; a toothedplate Within said opening; means for securing said plate to saidglobular member so asto have an opening entirely surrounding said plateand of substantially uniform 'vvidth; means for moving said cup aboutsaid globular inemberyeomprising a, rotary shaft having a member thereonoperativeiy engaging said toothed plate.

l. The combination with a globular member; of a cup member with anirregularly shaped opening therethrongh partly surrounding said globularmember and having a movable engagementtherewith; a plate Within saidopening having teeth in the edge thereof; means for moving said cupabout said globular member, comprising a rotary shaft having a memberthereon operatively engaging said plate; and means, as a member acqacentto Sfllfll pinion, for holding the same against endwise and lateralmovement.

5, The combination with aglobular men1- ber; of a cup member with anirregularly shaped opening therethrough and a shoulder paralleltherewith partly surrounding said globular member and having aInovable'engagement therewith: a toothed plate within said opening;means 101' moving said cup about said globular member, comprising arotary shaft having a member thereon operatively engaging said toothedplate; and means for holding said pinion in engage-- said mein shoulder.

globular metre ber; of a. cup member with an irregularly shapedopeningtherethrongh and a shoulder parallel therewith partly surrounding saidglobular member and having a movable engagement therewith; a platewithin said opening having teeth in the edge thereof; means tor movingsaid cup about said globib lai member, comprising a rotary shaft havinga member thereon operatively engaging said plate; and means for holdingsaid pinion in engagement with the teeth in said plate, said meanscomprising a disk having a rotary contact with said shoulder and and inrelation to said pinion so as to prevent axial movement thereof.

inent with the teeth in said 1:: ber having contact with said 6. Thecombination Wit; a

having a substantially straight slot therein; of a toothed cup member; amember on said and means ifor moving said (311p member about saidglobular member, said means comprisinga rotary, toothed, member hav ingengagement with the teeth in said can member.

8. In combination, a globular member having a substantially straightslot therein. and a hollow shank connected therewith; ot a toothed cupmember; a member on said cup member projecting into said slot and havingan operative engagement therewith; means for moving said can memberabout said globular member, said meanseomprising a shaft rotatablymounted in said shank; and pinion fixed 'thereto having a toothedengagement with teeth in said cap-member.

In testimony whereof I ofia my signature in presence of two Witnesses.
